Chidamber & Kemerer object-oriented metrics are a metric suite intended to monitor software quality. This repository describes the implementation of CKMetrics for VisualWorks.
- In VisualWorks connect to the publick repository in cincom
- In Store >> Published Items select
CKMetrics-corefor solely CKMetrics, orCKMetrics-fullfor CKMetrics and the Roassal-based visualizer - Load ckmetrics-full, to get the report calculator, and the visualizer, or load ckmetrics-core to get the report calculator with the basic metrics
For generate a report you can use the next script
| calculator |
calculator := CKCalculator new.
calculator addPackagesMatching: 'CKMetric*'.
calculator printResultOnDisk: 'myckmetricreport'
The method #addPackagesMatching: uses regular expresion to find the packages that you may want to measure. The previous code should generate a file with this output
CC 1.28421 Cyclomatic Complexity Returns the cyclomatic complexity....
LOC 1059 Number of Lines of Code Returns the number of lines of code, ...
LOCxC 34.1613 Number of Lines of Code per Class Returns the average number of lines of code per class
LOCxM 4.26842 Number of Lines of Code per Method Returns the average number of lines of code per method
LOCxP 176.5 Number of Lines of Code per Package Returns the average number of lines of code per package
NIV 65 Number of Instance Variables Returns the number of instance variables defined in the system
NOBugs 0 Number of Bugs Returns the number bugs(check comment of class CKNOBugsLED)
NOC 31 Number of Classes Returns the number of classes defined in the system

NOMiscellaneous 2 Number of Miscellaneous Returns the number of miscellaneous(check comment of class CKNOMiscellaneousLED)
NOMxC 6.12903 Number of Methods per Class Returns the number of methods per class
NOMxP 31.6667 Number of Methods per Package Returns the number of methods per package
NOP 6 Number Of Packages Returns the number of packages defined in the analyzed system.
NOPossibleBugs 0 Number of Possible Bugs Returns the number of possible bugs(check comment of class CKNOPossibleBugsLED)
NOUnnecessaryCode 1 Number of Unnecesary code Returns the number of Unncessary code(check comment of class CKNOUnnecessaryCodeLED)
With the visualizer, you can use the menu Tools>>Visualize CKMetrics Reports, to get a graph that shows all the reports that you previously created. And check the evolution of your app with lines of code, number of classes, by version.
